Application iledlAugust 22, 1901. Sera-1 N01 72,863. (NQmOBlJ To all whom it may concern,.-

Be it known that 1J AMES W. HODGES, a citizen of the United States, residing at Jersey City, in the county of`Hudson and State of New Jersey, have inventedcertain new and usefnllmproVements-in Steam-Traps, which improvements are fully set forth iny the following speciication and accompanying drawings, and in'the'latteri- Figure l is'a side elevation view of astearntrap constructed in accordance with my invention. Fig. 2 is a central longitudinal section of same asalongthe line a ct of Fig. 3. Fig. 3 is atransverse sectionthereof asv along Fig. 4 is 'a 'transverse section thereof as along theline cc of Fig. 1.

Similar reference numerals denote like parts throughout the several views of the drawings. i r f This invention relates to improvements in devices of thatl class commonly'iknown 4vas steam-traps, the same being -utilized for' the purpose of controlling thecondensationwater which accumulates in steam pipes or conduits.

The object of this invention is to provide a steam-trap which shallbe simple, inexpensive, and novel as regards construction, automatic., posi-titr,Y and reliable inoperation, which shall embody few,lif any,'fe'atures or elements liable' to disarra'ngeme'nt l`in nse, which shall be durable, and-.which shall posprior analogous structures. K p

The inventionvconsists in the employment of certainparts novel as to form, in the novel disposition and arrangement ofthe various parts, in certain combinations of the latter, and in certain .details of construction, all of which will be specificallyreferred to hereinafter, and set forth in the appended claims. HavingV reference. to'r the accompanying drawings, 2 is the body member, fitted at one end with a removable cap 2', communicating with the interior 0f which is the inlet-pipe 3. 3' is a diaphragm or transverse horizontal partition situated within the body member 2 somewhat distant from the lower end thereof. This diaphragm may be formed integral with the body member 2, as in the process of casting, or formed as a separate part and secured sess certain well-defined advantages over ldiaphragm 3'.

in position forservice, as by means of the fasteners 3". The body member2 is hollow or tubular in cross-section, sothat when the diaphragm 3' is located for service an outlet,-

chamber 4 atthe lower end of the body mem-- ber 2 is formed, which chamb'erhasv free communication .withthe outlet-pipe 4'. At the opposite end ofthe body member 2 there is located interiorlyof saidbodymember a re-V movable brace or diaphragm 5. This diaphragmmayfbeh'eld in position for service in any Well-'knownl and approved manner,

cording to theuvariations in the quantity of water of condensation that Inayaccumulate within the body member 2 above and at the The ioat 6'-is provided with a stern 6", which projects'upwardlytherefrom through a central orifice formed in the brace or diaphragm 5. Stem 6" carries adjustable stops 7 7', the former engaging said' stem below the diaphragm 5 and the latter engaging said stern above said` diaphragm'.3v Stop 7 servesto limit the rising,actiofoffthefioat 6', and stop-''servs to. limit'the'falli'ngaction" thereof.- Stops 7'7' are herelshown in the form` ofnnts working onftlir'eads T,with which the stein 6" is provided,"-butother devices, admitting 5 of adj ustment along the stem 6" and capable of limiting the rising and falling movements of the Hoat 6', may be sub stituted therefor. ,l

Float 6' is provided at its lowerend with a depending needleva-,valvej 7"', Vaiming-.with the orifice 7", formed centrally inthe diaphragm IOO the body member 2 between the diaphragrns 3 and 5 in any desired manner, as by way of suitable openings, as 8, formed in the diaphragm 5.

8 is a by-pass leading from the port 8, controlled, as by valve 9, to and communicating with outletfchamber 4.

It will be observed that by means of the stops 7 7 the movements of oat 6' may be regulated in accordance with the quantity of condensation-water to be taken care of, which water escapes downward through the orifice 7 and may be piped out of the chamber 4er otherwise conducted away. The upward movement of fioat 6 may be regulated to permit the escape by way of orifice 7"' ofthe maximum quantity of condensation-water, and the downward movement thereof may be accordingly regulated to permit due escape of the minimum quantity of such water. Therefore under these conditions all quantities of the water of condensation may be automatically taken care of.

In practice steam is permitted to pass through the trap as a whole by duly manipulating valve 9, and as the pressure of the steam at all points on the iioat 6 is equal the movements of said fioat, in accordance with the quantity of water of condensation that may accumulate in the trap, are accordingly facilitated.

It will be observed that my improved steamtrap is well adapted for the purpose for which it is intended and that the same may be modified to some extent without departing from the spirit and principle of my invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A device of the class herein described comprising a hollow body member having a 'valve-controlled outlet-port, as 8; a diaphragm within said body member below said port, and having an orifice, as 7; a float within said body member above said diaphragm, the said float being provided with a valve adapted to control said orifice; and means for limiting the rising and the falling movements of said iioat, the said body member being provided with a suitable inlet-opening substantially as herein specified.

2. A device of the class herein described comprising a hollow body member having a valve-controlled outlet-port, as 8"; a diaphragm within said body member, below said port, and having an orifice, as 7 a valve for controlling said orifice; afioat within said body member, above said diaphragm, the said float being adapted to rise and fall and in its movements control the actions of the valve last named; and means for limiting the rising and falling movements, respectively, of said iioat, the said body member being provided with a suitable inlet-opening, substantially as herein specified.

3. A device of the class herein described comprising a hollow body member provided with a valve-controlled outlet-port, as 8; a diaphragm within said body member, -below said port, and provided with an orifice, as 7 a brace fixed within said body member, above said port; a fioat within the body member, between said diaphragm and said brace and adapted to rise and fall, the said fioat being provided with a valve at its lower end for controlling the orifice in said diaphragm and with a stem at its upper end loosely engaging said brace; and stops, as 7 7', engaging said stem one above and the other below said brace and adapted to limit the rising and falling movements, respectively, of said float, the said stops each permitting of adjustment along said stem, and said body member being provided with a suitable inlet-opening, substantially as herein specified.

4. A device of the class herein described comprising a hollow body member having a valve-controlled outletport, as 8"; a diaphragm within said body member, below said port, and having an orifice, as 7; a brace fixed within said body member above said port and having a suitable central orifice; a float within said body member,bet\veen said diaphragm and said brace and adapted to rise and fall, the said float being provided with a needlevalve depending from the lower end thereof and adapted to control the orifice in said diaphragm, and with a threaded stem at its upper end projecting upwardly through the orifice in said brace; and nuts on said threaded stem, one above and the other below said brace, and whereby the rising and falling movements, respectively, of said fioat may be limited, the said body member being provided with a suitable inlet-opening, substantially as herein specified.
